Reaching efficiency through collaboration in membrane systems: Dissolution, polarization and cooperation

Sustainable Collaboration: Managing Conflict and Cooperation in Interorganizational Systems

Current interorganizational systems literature focuses on describing the role of information technology in enabling the transition from interfirm competition to cooperation. This article points out that the promise of IT enabled coop1 Izak Benbasat was the accepting senior editor for this paper. eration, ff not nurtured, can degenerate into conflict. The objective of this article is to identify...

Simulating Membrane Systems and Dissolution in a Typed Chemical Calculus

We present a transformation of membrane systems, possibly with promoter/inhibitor rules, priority relations, and membrane dissolution, into formulas of the chemical calculus such that terminating computations of membranes correspond to terminating reduction sequences of formulas and vice versa. In the end, the same result can be extracted from the underlying computation of the membrane system a...

Coordination, collaboration and cooperation

Cross-polarization for dissolution dynamic nuclear polarization.

Dynamic nuclear polarization (DNP) in combination with subsequent dissolution of the sample allows the detection of low-γ nuclei in the solution state with a signal gain of up to tens of thousand times compared to experiments starting from Boltzmann conditions. The long polarization build-up times of typically more than one hour are a drawback of this technique. The combination of dissolution D...

High-efficiency ultrasmall polarization converter in InP membrane.

An ultrasmall (<10  μm length) polarization converter in InP membrane is fabricated and characterized. The device relies on the beating between the two eigenmodes of chemically etched triangular waveguides. Measurements show a very high polarization conversion efficiency of >99% with insertion losses of <-1.2  dB at a wavelength of 1.53 μm. Furthermore, our design is found to be broadband and t...
